PROCESS OF TREATIlNG ORGANIC AND INORGAN IC MATERIALS.

To all wit-uni, it may concern Be it known that I, JAMES A. MCLARTY,

a subject of the King of Great Britain, and

a resident of Toronto, Canada, have invented certain new and useful Improvements .in Processes of Treating Organic and Inorganic Materials, of which the following is a specification.

My invention relates to improvements in the art of treating materials such as organic or inorganic materials, for the purpose of improving the valuable properties of said materials.

This process may be applied to various substances, for example metals, such as iron or copper, which when so treated acquire the properties of being rust-proof, also of being suitable for use as bearings, in that they will not heat up by friction, also the hardness and density of the metals is increased.

This process may also be applied to organic materials, for example, Wood, fabrics, leather and the like, and such materials when so treated become much more stable, that is they resist decay, and also resist the action of molds, bacteria, insect life, worms and other destructive agencies, for a much greater length of time, than the same materials when not so treated; a In carrying out my process, the apparatus illustrated in the annexed drawing may be employed, or other suitable apparatus may be used.

In said drawing the figure shows a vertical section of a container suitable for use in carrying out this process. a

In said drawing the container D is provided with a perforated shelf Q, for supporting the material "to'be treated, and this container is provided with a hinged lid or cover B, which is provided with a valved outlet A, for allowing the escape of gases, should the pressure in the vessel become era cessive.

The receptacle and its contents may heated either by means of the acket H which is provided with suitable inlets and Specification of Letters Patent.

bottom. of the container, a mixture containing a carbohydrate, for example sawdust, or wood shavings, or sugar, and a suitable hydrocarbon, such as crude petroleum oil, shown at K.

The perforated partitionC is then placed upon the lugs N shown in the drawing and the material to be treated is placed onthis perforated partition and the lid B is closed, thereby producing an air-tight receptacle containing the material to be treated, out of contact with the mixture including carbohydrate and hydrocarbon, whereupon heat is applied to the lower part of the receptacle, for the purpose of producing gases changes in the material being treated. The temperature to which the mass of carbohydrate and hydrocarbon is carried, may be from 200 to 400 F, and the length of time during which this temperature is maintained, may be about 1 to 3 hours, depending upon the temperature, size of materials being treated and various other conditions.

The chemistry of the process is rather obscure, and accordingly I deem it advisable not to confine myself to any particular theory, but merely state the actual steps which areperformed, and the results which are secure. v V

At the end of the heating period, the heat is removed from the bottom of the container, the valvein pipe A is opened, the lid B is removed from the container, and the materials are taken out, and are ready for" shipment or use capable of efiecting the desired comes rust-proof and this property is retained by the iron, even though the same be worked up by heating, into iron ohjects of any desired shape or size. -The iron also isniuch more malleable and can be welded with great faciiity,

Copper when treated by this process is made very much harderthan ordinary coper, is rendered especially suitable for se in bearings, since it shows no tendency up. lin this connection I will state that of copper and pinion steel have been at a speed of 1880 revolutions per mi etc without any lubrication whatever .-ithout generating any heat, and with 1g any signs wear.

3 out she lit is also to he noted that metals when so are purified from such substances as 'liti phosphorus and the like, which makes the process especially valuable in the treatment of pig iron, high in phosphorus.

Coal when treated according to this process, appears to show a considerable increase in its calorific power.

Wood and other organic materials, when treated according to this process do not change materially in physical appearance, although it becomes proof against atmospheric influences, and moreover does not check, crack, decay, nor is it subject to insect attack. Wood treated in this manner also burns less readily than untreated wood.

This method of treating. organic materials isclaimed in my copending application 756,031, filed March 21, 1913.

What I claim is 1. A process of treating materials of. the classes set forth, which-comprises subjecting said materials in a closed vessel to the action of the gases and vapors evolved by heating a mixture including a'carbohydrate and an oil, said mixture being out of contact with said materials. 1

2. A process of treating materials of the classes set forth, which comprises subjecting said materials in a closed vessel to the action of the gases and vapors evolved by heating a mixture includin cellulosic material and mineral oil, said mlxture being out of contact with said materials.

3'. A process of treating materials of the classes set forth, which comprises subjecting said materials in a closed vessel to the action of the gases and vapors evolved by heating a mixture including saw dust and crude petroleum, said mixture being out of contact with said materials.

4:. A process of treating materials of the classes set forth,which comprises subjecting said materials in a closed vessel to the action of the gases and vapors evolved by heating a mixture including a carbohydrate and an oil, said materials being out of direct contact with said mixture, and also out of contact with air.

5. A process of treating metals,.to harden the same, and to prevent corrosion thereof, which comprises subjecting said metals to the action of the gases and vapors evolved by heating a mixture including a carbohydrate and crude petroleum, said mixture being out of contact withsaid metals. i

6. A process of treating copper to harden the same, and to remove or reduce the tend-- ency of the same to generate heat by friction, which comprises subjecting said copper to the action of the gases and vapors evolved by heating a mixture including a carbohydrate and crude petroleum, said mixture being out of contact with-said copper. v

7 A process of treating metals to harden the same, and to prevent corrosion thereof, which comprises subjecting said metals to the action of the gases and vapors evolved by heating a mixture consisting of a carbohydrate and crude petroleum, said mixture being out of contact with said metals.

8. A process of treating copper to harden the same, and to remove or reduce the tendency of the same to generate heat by fricf tion, which comprises subjecting said copper being out of contact with said copper.
